German TADF developer Cynora presented its latest blue TADF material in May 2018 - with a CIEy of 0.14, EQE of 20% and a lifetime of 20 hours LT97 at 700 nits. Cynora expects to have blue material in the mass production by 2020.

Cynora's Chief Marketing Offer, Dr. Andreas Haldi was kind enough to answer a few questions we had regarding TADF emitters, the differences between next-generation emitter technologies, lifetime, color points and more.

New sensor technologies are being developed specifically for the integration of fingerprint scanning functionalities with OLED displays. The recent announcements indicate that the industry is moving away from capacitive sensors to focus their efforts on optical or ultrasonic detection. For display manufacturers, this could even present opportunities to innovate and offer their own solutions.

Once a premium feature, fingerprint sensors have become almost standard on smartphones. However, the latest design trend is to remove the bezels around the display, leaving no room for the fingerprint sensor. Some OEMs made the choice to move the sensor to the back of the device, which is not always convenient (for instance when mounted on a car dash).

Futaba launched its flexible (film-type, curvable) 1.8" 160x32 monochrome white PMOLED back in November 2015, and we have now added this interesting panel to our OLED Marketplace.

If you are interested in this display for your device or new project, contact us now, or check out more information over at the OLED Marketplace.

Today we published new versions of our market reports - that cover the flexible, transparent, VR/AR, microdisplays, automotive and graphene OLED markets. OLED-Info provides comprehensive niche OLED market reports, and our reports cover everything you need to know about the niche market, and can be useful if you want to understand how the OLED industry works and what this technology can provide for your own industry. The reports are now updated to July 2018.

The OLED for VR/AR Market Report:

• Why OLEDs are adopted in almost all VR HMDs
• What kind of displays are required for VR and AR applications
• What the future holds for the VR and AR markets
• Current and future VR and AR systems

The report package provides a great introduction to the emerging VR and AR market, and details the role that OLED displays will have. Read more here!

The display industry's top conference, SID DisplayWeek 2018 took place at the end of May in Los Angeles. As always, we found this trade show to be very interesting - especially as OLED is quickly becoming the technology of choice for many applications. SID also gave us the chance to check out other technologies such as Micro-LEDs, next-gen e-paper displays, quantum dots and more. Here's a list of all our articles from SID:

• Samsung Display - rollable, transparent, automotive and more!
• Samsung Display - new VR AMOLED displays
• LG Display - VR OLEDs, 77" transparent and flexible panel, and more!
• BOE - flexible and foldable AMOLEDs
• BOE - 0.39" FHD OLED microdisplay
• BOE - ink-jet printed OLED prototype
• Visionox - PMOLED and AMOLED prototypes and displays
• Visionox - transparent OLED prototype
• Visionox - blue TASF OLED device
• Tianma - foldable, flexible and rigid AMOLEDs
• AUO - OLED and Micro-LED prototypes and displays
• Kyulux/Wisechip - 1.71" flexible Hyperfluoresence PMOLED
• Futaba - automotive, flexible and transparent PMOLEDs
• The Fraunhofer's LOMID 1-inch OLED microdisplay
• Amorphyx's quantum-tunneling display backplanes
• The EU's €14 million Lyteus OLED lighting initiative
• Coherent summarizes the differences between LCDs, OLEDs and Micro-LEDs

In January 2015 the EU launched the LOMID project to develop next-generation large-area OLED microdisplays, and in 2017 the partners in the project announced the production of a 1-inch diagonal 1200x1920 (2,300 PPI) 120Hz curved OLED microdisplay.

The Fraunhofer FEP demonstrated this panel at SID 2018, as you can see in the video above. The institute also demonstrated a new design which uses two such panels and special optics to provide double the resolution for each eye.

US-based Amorphyx develops amorphous-metals based display backplanes, which can be used to drive displays using quantum-tunneling. The company says that such backplanes will enable extremely fast conductivity and thus "unlimited" refresh rates.

Producing such backplanes is also said to be easy as it uses less layers compared to TFT backplanes, using its Amorphous Metal Non-Linear Resistor (AMNR) technology. AMNR backplanes are suitable for LCDs, OLEDs and e-paper displays. This is still an early-stage technology, but the company demonstrated some prototypes at SID and it will be interested to see if this technology can progress in future years.

Tianme had an large booth in SID, showcasing many display technologies and demonstrating its latest LCD and OLED panels. Tianma started producing rigid and flexible OLEDS in April 2017 at the company's 6-Gen fab in Wuhan, and at SID the company demonstrated its 5.5" on-cell rigid AMOLEDs now in production. Tianma told us that this display was adopted in smartphones by Lenovo and Asus.

Tianma also demonstrated several flexible OLEDs in many configurations which we will list below. Almost all of the panels were based on the same basic display - a flexible 5.99" WQHD 1440x2280 (537.5 PPI) AMOLED produced on a polyimide substrate. Tianma showed this panel in a regular design, and also in a notch-type design.

Taiwan-based AU Optronics (AUO) demonstrated the company's latest OLED, LCD and Micro-LED technologies at SID 2018.

The company had a relatively small OLED demonstration area, showing its True-Circle in-cell Touch AMOLED displays (1.2" and 1.4") unveiled in May 2017. These displays are already shipping. AUO also unveiled its large 13" transparent AR AMOLED (68% transmittance). This transparent OLED was shown for the first time. The 13" panel features a resolution of 1150x575 (100 PPI) and a brightness of 200 nits.
